  • The appendicular skeleton is composed of the bones of the arms, hips, legs and shoulders.
  • Bones can be categorized by shape: flat, irregular, long, and short.
  • Joints can be categorized by their structural components—cartilaginous, fibrous, and synovial—or by their function—amphiarthrosis, diarthrosis, and synarthrosis.
  • Endochondral bones form from cartilage pegs in the embryo—they usually produce long bones and parts of irregular and short bones. They have primary and secondary ossification centers, and a region that produces the bone collar.
  • Dermal bones form in subcutaneous membranes, are mostly composed of cancellous bone with a covering of boney plates and usually produce flat bones and parts of irregular bones.

  • Gather, read, and evaluate scientific and/or technical information from multiple authoritative sources assessing the evidence and usefulness of each source in relation to work-related musculoskeletal disorders.

Understanding

Students understand that:
  • The arrangement of muscles enables them to work congruently to yield an assortment of movements. In order for these movements to take place the muscular system must work with several other body systems (skeletal, circulatory, nervous). Muscles function produces movement, stabilizes joints, maintains posture and body position, generates heat, and assists in protecting internal organs.
  • There are several phases that lead to muscle fiber contraction. At the neuromuscular junction the muscle fiber is activated so that there is a change in membrane potential which precipitates the formation of an electrical current (action potential). This action potential is then disseminated along the sarcolemma which prompts a rise in calcium ions that in turn leads to the stimulation of muscle contraction. In a disease such as Duchenne muscular dystrophy (DMD), the patient's sarcolemma tears during a contraction which permits extra calcium ions that damages contractile fibers, lymphocytes, and macrophages that accumulate in surrounding connective tissue. This homeostatic imbalance causes the damaged cells to atrophy resulting in a debilitating loss in muscle mass for the patient with DMD.
  • Work-related musculoskeletal disorders/ injuries are a major concern for employers. Therefore it is imperative that ergonomic design solutions prevent and or reduce the incidence of these disorders. Annually, these disorders/injuries cost employers vast amounts of money, time, and resources. With that said, employers are continually seeking ergonomic design solutions to remedy this dilemma.

This nervous system is responsible for aiding and sustaining homeostasis in the human body where it monitors and analyzes environmental information and responds).
  • Homeostatic imbalances may occur in the brain for various reasons. The causes of these imbalances include traumatic brain injuries (contusions, concussions), degenerative brain disorders (Alzheimer's disease, Parkinson's disease, Huntington's disease), and cerebrovascular accidents (strokes).
  • Degenerative brain disorders such as Alzheimer's disease occur when beta-amyloid peptide deposits and neurofibrillary tangles occur. These tangles are delineated by an insufficiency of the neurotransmitter acetylcholine. Whereas degenerative disorders such as Parkinson's disease and Huntington's disease are caused by too much or too little of the neurotransmitter dopamine. Treatments for the symptoms of these diseases include medications such as acetylcholinesterase inhibitors, glutamate pathway modifiers, and MAO-B inhibitors). These medication treatments are not a cure for the diseases; they only slow disease progression. Research for new medication therapy is ongoing with the hope of developing better medications that halt the disease process and have minimal adverse side effects.

Knowledge

Students know:
  • Arteries and arterioles carry blood from the heart to the rest of the body.
  • Veins and venules carry blood from the body to the heart.
  • Capillaries are small blood vessels that exchange materials with tissues.
  • Vasoconstriction is the narrowing of a vessel while vasodialation is the widening of a vessel.
  • The heart is made of mycardium covered by pericardium and is composed of four chambers.
  • The left half of the heart controls systemic circulation while the right half controls pulmonary circulation.
  • One pumping action of the heart is called the cardiac cycle—diastole is the filling of the atria and ventricles and systole is the emptying of the ventricles.
  • Blood is composed of plasma and formed elements and transports materials needed to maintain body homeostasis.
  • Blood cell types: 1) RBC's—contain the protein hemaglobin which transports oxygen and carbon dioxide 2) WBC's—granulocytic (basophils, eosinophils, and neutrophils) produce secretions that kill micoorganisms and agrnulocytic (lymphocytes and monocytes)—lymphocytes produce an immune respons and monocytes are phagocytic. 3) Platelets—assist with blood clotting.
  • Blood cells are produced in the bone marrow by hematopoiesis and are derived from a multipotent stem cell.
  • Blood type is a way of categorizing RBCs according to variations in proteins on the cell membrane surface—these proteins can be classified as types A, B or D.
  • Diseases of the cardiovascular system affect either blood vessels or the heart and are either congenital, produced by lifestyle factors, or produced by microorganisms.
  • Common vascular diseases interrupt blood flow while common heart diseases prevent the chambers and/or valves from working properly.
  • Electrocardiography measures the electrical activity of the heart.
  • Pulse is an indicator of heartbeat and heartbeat is produced by blood pressure.
  • Heart rate is the number of cardiac cycles per minute.

Skills

Students are able to:
  • Gather, read, and interpret scientific information about the cardiovascular system, including its structures and their function.
  • Use a model to predict and show relationships among variables between the cardiovascular system and its components.
  • Gather, read, and interpret scientific information about the ABO blood groups.
  • Use models to relate structure to function for the components of blood.
  • Gather, read and interpret scientific information about pathological conditions that may affect the cardiovascular system.
  • Gather, read and interpret scientific information about possible prevention options related to the pathology of the cardiovascular system.
  • Gather, read and interpret scientific information about possible treatment options related to the pathology of the cardiovascular system.
  • Use evidence to form an argument about possible prevention or treatment options related to the pathology of the cardiovascular system.
  • Use evidence to defend an argument about possible prevention or treatment options related to the pathology of the cardiovascular system.
  • Evaluate counter-claims and revise argument based on evidence.
  • Gather, read and interpret scientific information about common tests that can be used to monitor cardiovascular function.
  • Design a experiment to collect data in relation to cardiovascular function.
  • Determine how the change in the variables will be measured or identified.
  • Determine how the response within the cardiovascular system will be measured or identified.
  • Use a tool to collect and record changes in the external environment (variables) and the organism responses.
  • Evaluate experiment for accuracy and precision of data collection, as well as limitations.
  • Make revisions to experiment if needed to produce more accurate and precise results.
  • Manipulate variables that will cause changes in cardiovascular test investigation results.

Understanding

Students understand that:
  • The cardiovascular system's main function is to transport various items throughout the body (oxygen, digested nutrients, systemic waste, etc.).
  • Various cardiovascular organs serve in different capacities to move blood (its transport agent) around the body.
  • Cardiovascular organs are made up of various tissues that work together to carry out the organs' functions.
  • Several variables such as exercise, diet, disease, caffeine, etc. affect cardiovascular health.
  • Lifestyle changes can be used to prevent or treat cardiovascular disease.
  • Several variables such as exercise, diet, disease, caffeine, etc. change cardiovascular output.
